Therefore thus saith the LORD; Behold, I will punish Shemaiah the Nehelamite, and his seed: he shall not have a man to dwell among this people; neither shall he behold the good that I will do for my people, saith the LORD; because he hath taught rebellion against the LORD.
Jeremiah 29:30 Then came the word of the LORD unto Jeremiah, saying,
Jeremiah 29:31 Send to all them of the captivity, saying, Thus saith the LORD concerning Shemaiah the Nehelamite; Because that Shemaiah hath prophesied unto you, and I sent him not, and he caused you to trust in a lie:
Jeremiah 29:32 Therefore thus saith the LORD; Behold, I will punish Shemaiah the Nehelamite, and his seed: he shall not have a man to dwell among this people; neither shall he behold the good that I will do for my people, saith the LORD; because he hath taught rebellion against the LORD.
The verse centers on "therefore", "thus", "saith", "lord", "behold", "punish", "shemaiah", and "nehelamite". It is saying that the verse draws attention to "therefore" and "thus", so its meaning should be read from those terms before moving to application.
The prior verse says "Send to all them of the captivity...", giving immediate footing for "therefore" and "thus". In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "thus" with trust shaped by these words, not by a vague optimism outside the passage.
